Prestress steel wire rope strengthened concrete beam construction method
The invention discloses a prestress steel wire rope strengthened concrete beam construction method characterized by comprising the construction steps that (1) prepunched holes are drilled in designated positions of two corners of the bottom of a steel beam; (2) concrete of the lower portion of a concrete beam is chiseled away, a main bar is exposed, and the steel beam and the main bar are welded;(3) whitewash on the surface of a brick wall is peeled, an annular brick groove is drilled, and a steel plate forming a steel anchoring hoop penetrates through the annular brick groove, and a whole isformed through welding; (4) a reserved hole is drilled in a concrete floor; (5) central pivot steel wire ropes penetrate through the prepunched holes in the bottom corners of the steel beam to be fixed to the steel anchoring hoop, and turnbuckles between the steel wire rope and the steel anchoring hoop are installed; (6) prestress is applied to the central pivot steel wire ropes through the turnbuckles; (7) gaps between the steel wire ropes and the reserved hole of the concrete floor are closed by high-strength glue; and (8) whitewashing is conducted with high-strength mortar on the two sidesof the concrete beam.
本发明公开了一种预应力钢丝绳加固混凝土梁施工方法，其特征是施工步骤包括：(1)在钢梁底部两个角部指定位置钻设预穿孔；(2)凿除混凝土梁下面的混凝土，裸露出主筋，将钢梁与主筋进行焊接；(3)剥离砖墙表面粉刷，钻设环形砖槽，组成钢锚固箍的钢板穿过环形砖槽焊接成整体；(4)在混凝土楼板钻设预留孔；(5)将中支点钢丝绳穿过钢梁底部角部的预穿孔固定在钢锚固箍，安装钢丝绳和钢锚固箍之间的花篮螺栓；(6)通过花篮螺栓对中支点钢丝绳施加预应力；(7)用高强胶封闭钢丝绳和混凝土楼板预留孔之间的空隙；(8)混凝土梁两侧采用高强砂浆进行粉刷。
